' FLUSHING-TANK FOR WATER-CLOSETSL Specification of Letters Patent.

Patented June 6, 1916.

Application filed April 14:, 1915. Serial No. 21,234.

architect, a subject of the King of Prussia,

German Emperor, residing .at 10 Blumen thalstrasse, Magdeburg, Germany, have invented new and useful Improvements in Flushing-Tanks for Water-Closets, of which the following is a specification.

This invention relates to siphon flushingcisterns for water-closets and the like and has for its object to provide alternatively a part or whole discharge ofthe tank merely by the well known traction of a chain at the lever fulcrumed on the walls of the tank and connected to the top of the single hood or cup inverted over the discharge limb.

It consists in general in that the discharge pipe is divided in the height of the level of the water to be retained after the part discharge; an upper part on the pipe prolonging the aforesaid pipe to the water-level of the whole filling or full discharge being connected to the cup or hood, and that an air valve is provided in the cup admitting the airto the interior of the cup when in continuous lifting of the cup the water-level has sunk to the limb or margin of the lower part of the discharge pipe.

In the drawing Figure 1 is a vertical section through the tank and the flushing device therein, showing the ordinary ball cock supply valve or float operated valve for controlling the supply; the tank filled up. Fig. 2 the same section in which all means are in the position of partly discharging the tank.

a is the tank, I) the supply valve, 0 the discharge pipe, the continuation d of which, without the tank runs to the water-closet. The discharge pipe 0 within the tank projects about a or 6% of the ordinary length of discharge pipe; the wanting quarter or fifth of the length to let the tank-be filled with the usual quantity or height of water is formed by a short piece of tube 6, guided axially on the discharge pipe. This tube 6 is connected, a certain distance from the top, to the hood so that, in the lowered position of the hood, the jointed discharge tube 0, e, and the hood or inverted cup f show nearly the same arrangement or position as the flushing apparatus in common use.

In the mantle of the hood 7 a valve is provided, represented in the drawing by. a hole 9, and a disk or plate h which is held in position and pressed to the hole 9 by a plate springs secured to the discharge tube or the tank bottom. The hole in the mantle of the hood is provided in such a height, that in lifting the hood the hole overcomes the upper margin of the lower discharge tube 1\yliile the disk h remains and uncovers the The operation of the device is as follows If only a small flushing is desired the traction of the chain should be continuous; thereby the hood is lifted and with it the additional discharge tube 6; the water flushes between the under margin of the tube 6 and the upper margin of tube 0 through tube a to the closet, the water level sinks unto the limb of discharge tube 0 and unto the hole 9 in the mantle of the hood,-Fig. 2 of the drawingand the here entering air destroys the vacuum under the cup thus ceasing the action of the siphon. If full flushing is desired the traction must be short; thereby the water falls between both parts 6 and 0 of the discharge tube downward and by immediately lowering the hood and with it the tube-piece e, the siphon begins to work over the upper margin of tube 6 in the well known manner and since hole 9 is then covered the cup or hood being in lowered position, the whole contents of the tank is sucked out.

What I do claim and desire to secure by Letters Patent is: V

1. In combination with the tank a discharge tube extending only to a height be fastening the additional tube to the hood, a name to this specification in the presence of hole in the mantle of the hood, a plate covtwo subscribing Witnesses. ering said hole, a plate spring connected to said plate and t0 the tank, and means for VVILHELM MESCH. 5 lifting and lowering said hood and its adlVitnesses:

joint tube, substantially as set forth. CLARA PETERS, In testimony whereof I have signed my ERICH PETERS.
